JPL Update Danan Dong Michael Heflin Sharon Kedar Brian Newport Frank Webb JPL Status Report, SCIGN Annual Meeting, 4/26/2004
Overview • GIPSY Processing status • NASA REASoN Project Status JPL Status Report, SCIGN Annual Meeting, 4/26/2004
Processing • Bias fixing strategy • 5-7 Clusters per day • CPU intensive • Sensitivity to station outages • 1 Cluster per day constructed from baselines • Distributable across many CPUs • Insensitive to station outages • Developed and tested last year • Implemented in April 2003 • Moving to web services for antenna metadata • New GIPSY version in Nov. 2003 JPL Status Report, SCIGN Annual Meeting, 4/26/2004
Solutions • Complete through March 31, 2004. • Available on internet • Free network • Raw solutions • Loose covariance • Accounts for frame noise JPL Status Report, SCIGN Annual Meeting, 4/26/2004
REASoN • Reminder of Our Goals • How we are organized • A High Level Requirement • High Level Architecture • Baseline Schedule • Status JPL Status Report, SCIGN Annual Meeting, 4/26/2004
REASoN Goals • Apply modern IT methodology within SCIGN to: • Produce and disseminate higher-level data products to a larger community • Scientists • Government agencies (Federal, State, and Local) • Surveyors • GIS professionals • Product levels adopted by PBO JPL Status Report, SCIGN Annual Meeting, 4/26/2004
REASoN Goals • Build on current capabilities within SCIGN for data archiving, information systems, and data analysis to disseminate the following products: • Geodetic position time series • Crustal motion models • Strain rate maps • Geologic fault models • Near-real-time earthquake response information • Geodetic reference systems for precise GIS and surveying • Improve capabilities in • Archiving • End-user interfaces • Delivery mechanisms • Data modeling • Open source project based on a redundant, multi-tiered “Virtual Archive” for GPS applications. JPL Status Report, SCIGN Annual Meeting, 4/26/2004
How we are organized • Around Four systems • Product Input • Seamless Archive • Web services • GPS Data Processing • GAMIT and GIPSY • Product Generation • QOCA Based • Product Output • Virtual Archive • Web services • Meta data • Products • Plus two NASA requirements • NASA SEEDs participation • Standards Working Group • Open Source Project • Virtual Archive JPL Status Report, SCIGN Annual Meeting, 4/26/2004
A High Level Requirement • Need • Processing centers and processes use the same input data • Goal • All processing retrieves data from a common source • Objective • Seamless Archive • Web services • Pull data at time of analysis • Push results into archive • Pull products from archive for distribution JPL Status Report, SCIGN Annual Meeting, 4/26/2004
